Marigold Care

Marigolds are easy plants to grow and take care of. Meeting their basic light, water temperature, soil and pruning requirements should be enough to ensure the plant flourishes. 

Marigold Light Requirement

Flowering plants like Marigolds require sufficient access to direct or full sunlight to be able to produce perfect blooms and stay flourishing.

Too little sunlight for the elegant plant would lead to its leaves looking leggy and a stunted growth with little flowering. 

When growing the Marigold flower indoors, be sure to place the potted plant in a room that has as much access to direct sunlight as possible. Keep it next to an eastward-facing window or on an eastward-facing balcony as Marigolds make excellent balcony plants. 

Marigold Water Requirement

How frequently you water your Marigold flower depends on the age of the potted plant. A week-old Marigold would require watering every day to establish a good root system.

Once the root system is well established (which oftentimes, takes a week), you can then limit watering the Marigold flower to once a week. 

During hot seasons like the summer or spring, increase watering frequency to once in 4 days, and during the winter and fall seasons, limit watering to once in 2 to 3 weeks.

Use room temperature dechlorinated water so as to avoid stressing the plant’s delicate roots. And ensure you water into the soil, not the Marigold plant. 

Marigold Soil Requirement    

The Marigold flower is not picky about the soil type being used. Ensure that whatever garden soil is being used is a well-draining soil type. 

The soil type used should also possess slight moisture-retaining ability which can hold in a little moisture during dry seasons. 

Keep the soil level in the range of neutral to a little acidic. A perfect pH range would be between 6.0 to 7’0.

Adding organic matter to the plant soil is unnecessary as the plant would flourish more when grown in lean soil.

Marigold Propagation and Potting Requirement

Marigold flowers can be propagated in two ways, these are;

  • Through Stem Cuttings
  • Through  Seed Propagation.

The easiest of the two methods is seed propagation, however, both methods require little effort. 

A Marigold plant is small in size and an annual, fast-growing plant, so repotting would not be necessary. Use a small pot that contains enough drainage holes at the base to allow for the  easy flow of water out of the pot. 

Marigold Pruning Requirement

Marigold Pruning Requirement

Regular pruning and deadheading of the Marigold plant would help the plant grow in a proper manner. 

It is recommended that you sterilize all tools to be used for pruning and that you wear protective gloves before pruning the potted plant.
